A pumping'mechanism is used with the inven- -tion and this pumping mechanism may ;be in- ..serted into. the. container or removed therefrom .ior .use with a .separate container. The pumpingmechanism is. of the pressure type :but the -tanker ,containerinto-which the liquid isdeposited .is ,not necessary in order thatpressure may ibelbuiltup asthe pump is provided withla tank or container l9 into whichtheliquidis pumped and fromwhich it is pumpedunderpressure. The container; l 9 may beproperly. termed apumpchamber." This p mp chamber: |9 -is provided with a top or. cover 158 through cwhichis ex ended theru'n b c linde f se, h vinga thr de "'end'omwhichtheglandlll is threaded to retain the packing H in close fit about the piston rod 29 which projects therethrough and which is attached at its inner end to a piston 21 slidably mounted in the cylinder 69. This cylinder 69 is in communication through the pipe 22 with the interior of a housing or fitting 23 and posi tioned in this housing 23 is a valve seat 24 having an opening 74 formed therethrough. A ball 25 is adapted to engage the valve seat 24 and close the passage or opening 14 therethrough. Threaded into the upper end of the housing 23 is a collar 26 having a passage 15 formed therethrough. The collar 25 is threaded into the bottom 13 of the pump barrel l9. Threaded into the lower end of the housing 23 is a fitting 21 having a passage 29 formed therein communicating through a lateral opening I! with the interior of the container IS in which the pumping mechanism is positioned. This fitting 21 is provided with a valve seat on which rests a ball valve 28 which serves to close the passage 29. A nipple 30 projecting downwardly from the fitting 21 projects through the bottom iii of the container [5. This nipple 3B is threaded for reception of a nut 18 which serves to clamp the bottom It against the gasket 31 and provide a leak-proof connection.

The construction is such that as the piston 21' is reciprocated in the cylinder 69 the ball valves 25 and 28 alternately open and close. On the upward stroke of the piston 2:i 1the ball 28 is raised from its seat while the ball 25 is forced or pulled downwardly onto its seat. On the upward stroke of the piston 2! liquid is drawn inwardly through the passage 11 and 29. On the downward stroke of the piston the liquid is forced against the ball valve 28 which moves onto its seat and the liquid under pressure serves to raise the ball 25 off its seat and passes upwardly through the passage T into the interior of the pump barrel i9.

As the liquid is forced into the pump barrel IS a pressure will be built up and the liquid may then flow outwardly through the pipe 32 which communicates with the interior of the pump barrel l9. An elbow 33 affords a means for connecting a nose 33A in communication with the pipe 32.

Connected to the upper end of the piston rod 20 is a rod 34 having the angularly turned end 34A. This rod 34 telescopes with a tubular rod 35 having the angularly turned end 36 which is projected through an opening in the rocking arm 31 which is pivotally mounted at its lower end to a bracket 38 which is mounted on and projects outwardly from the tank 15. When the rod 34 is telescoped in the tube 35 it may be locked in position by the set screw 48 and a clip 39 may be fastened around the rod 34 and the member 3! to retain these parts in parallel closely spaced apart position.

When it is desired to operate the mechanism the rod 34 is drawn outwardly of the tube 35, as shown in Fig. 12, and locked in the proper position by set screw 40. A rocking of the arm 31 will then effect a reciprocation of the piston rod 20 to accomplish the desired pumping. The use of the telescoping rod 34 makes it possible to reduce the device to a compact form when it is not operating.

As shown in Fig. l, and Fig. 2, the container i5 is provided with a handle 15 and with a cover 14 which covers the inlet opening. This .con-

tainer is also provided with a strap, as shown in Fig. 12, the strap 19 having a hook 80 at its free end. The operator would carry the container "i by hooking the hooks on the lower edge of the container l5 and the straps extending over the back.

The hose 33A may be fastened in the bracket 4| when it is desired to transport the mechanism with the hose 33A attached to the elbow 33.

A nozzle is used on the end of the hose 33A and in the present invention I have used a novel type of-nozzle comprising a fitting 42 which is attached to the end of the hose 33A. This fitting 42 is threaded into one end of a housing 43 so as to compress the gasket 46. Fitted on the 0pposite end of the housing 43 is a tip 44 which serves to compress the gasket 45. The chamber 41 is formed in the fitting 42 in communication with the interior of the housing 43. The end of this chamber is provided with a valve seat 19. Positioned in the housing 43 is a tubular adjusting core 50 having a plurality of circumferentially directed ribs 8| formed thereon which serve to provide rack teeth. For rned on one side of the housing 43 is an enlargement 43A having an opening in which is positioned a pinion 49 on which is mounted a head 48 whereby the pinion 49 may be rotated. A gasket 84 and a nut 83 threaded on the threaded ends of the pinion 49 serve as a means for mounting pinion on the housing enlargement 43A. The pinion 49 and the teeth 8| on the core 50 operate as a rack bar and pinion, a rotation of the member 49 effecting a longitudinal slidable movement of the core 58 in the housing 43.

The adjusting barrel or tube 50 is provided adjacent its rear end with a plurality of inlet openings 5| through which water may enter into the interior thereof. A plurality of outlet openings 53 are formed at the forward end of the adjusting barrel or tube 50. The end of this barrel or tube 50 is tapered as at 54 to provide a valve surface. Formed spirally in this surface 54 are grooves 56 communicating with a peripheral groove 55 in which the openings 53 are formed. Loosely positioned in the rear open end of the barrel 50 is a valve stem 51 on which is mounted the valve head 58. This valve head 58 is of a size that it may close the barrel 59 at its open end. The bottom of the chamber 41 is provided with a valve face 19a against which the valve 58 may engage.

Construction is such that when water is delivered under pressure through the bore of the fitting 42 and the parts are moved to the position shown in Fig. 6, the valve 58 will serve to effectively close the passage 85 and preventpassage of water therethrough thus the operator may by rotating the head 46 shut off the flow of water through the hose and nozzle. If the operator desires to deliver through the nipple 44 of the nozzle a quantity of liquid the head 48 would be rotated so as to slidethe adjusting barrel 50 to the proper position. This adjusting barrel 50 moves to the left of the position shown in Fig. 6, the valve 58 will move off of its seat and liquid would be permitted to enter chamber 41 and then flow around the barrel 50 into the housing 43. A quantity of the liquid would also flow through the opening 5| into the barrel 50 and outwardly through the openings 53. Should the member 50 be moved but a slight distance to the left of the position shown in Fig. 6, a stream of liquid would bev delivered from the nipple 54 as this movement continues toward the position shown in Fig. 5, this stream of liquid would be cut down and an atomization or break ing up of the stream would take place. When the valve is moved to its fully adjusted position shown in Fig, 5, the surface 54 cooperating with the conical inside walls of the nipple 46 would operate as a valve and the only escape for the liquid would be through the spirally arranged passages or grooves 56. This would result in the delivery of a very fine spray or mist from the nipple 44. Thus it is possible by moving the barrel 50 longitudinally of the housing 43 to adjust the stream of liquid emitted from the nipple 44 from a steady stream to a very fine mist. This is important particularly if the device is used for spraying a solution on plants and the like. It is also important that a steady stream or full flow of liquid be permitted when it is desired to reach high places such as the tops of trees or when it is intended to use the device as a fire fighting apparatus.

It will be noted that the nozzle may be very easily and quickly taken apart and placed to gether thus making it possible to clean and adjust or repair the various parts of the nozzle.

Experience has shown that with a spray device constructed as illustrated a very economical structure is provided and one Which will function most efficiently.
